Explanatory Notes

Example Unit Entry (battalions, regiments, brigades)

308th Cavalry Regiment (62d Cavalry Division) Organized Reserve Maryland/Pennsylvania

HQ—Cumberland, MD, 1921–22; Pittsburgh, PA, 1923–41

Demobilized 22 December 1918 at Camp Kearny, CA, as the 65th and 66th Field Artillery 

Regiments, and on 21 December 1918 as the 22d Trench Mortar Battery. All elements reconstituted 

in the Organized Reserves on 15 October 1921 and consolidated as the 308th Cavalry, assigned 

to the 62d Cavalry Division, and allotted to the Third Corps Area. Organized 10 November 1921 

with regimental headquarters at Cumberland, MD. Regiment relocated about October 1922 to 

western Pennsylvania. Regimental headquarters concurrently organized at Pittsburgh. Reorganized 

1 July 1929 as a three-squadron regiment. Concurrently, entire regiment relocated to Pittsburgh, 

PA. Typically conducted its Inactive Training Period meetings at the 107th Field Artillery’s Hunt 

Armory at the Post Office Building in Pittsburgh. Members built the 308th Cavalry Club in 1928 on 

property owned by the Aspinwall Hospital in Aspinwall, PA, and conducted some Inactive Training 

there. Facilities included equestrian, pistol, and saber training areas. Conducted regular equestrian 

training with the horses of the 107th Field Artillery. Conducted summer training with the 3d Cavalry 

Regiment at Fort Myer, VA, and at Fort Belvoir, VA. Trained with the units of the 52d Cavalry 

Brigade at Mount Gretna, PA, in July 1928. Conducted cavalry Citizens Military Training Camp 

(CMTC) training at Fort Myer as an alternate form of training. Designated mobilization training 

station was the York Concentration Area, PA. Location 7 December 1941—Pittsburgh, PA.

Organization Day: 24 February. Chosen to commemorate the regiment’s organization on 24 February 1918.

Status: Disbanded 11 November 1944 as the 66th Tank Destroyer Battalion.

Purposes and Scope

The purposes of US Army Order of Battle 1919–1941 are threefold. The first is to fill a void in the 

published record of US Army units documented by Order of Battle of the United States Land Forces in 

the World War published by the Center of Military History and Mr. Shelby L. Stanton’s Order of Battle, 

U.S. Army World War II. The second is to provide Army command historians, unit historians, and other 

individuals who are trying to research specific unit histories a basic overview of what these units were doing 

in the interwar period, where the units were located, and who commanded them. The third is to provide 

a private individual who had a relative who served during this period, and who wishes to know what that 

service may have consisted of, an account of the major activities in which the relative’s unit was involved. 

The scope of the work covers units from the size of separate battalions from all arms and services to field 

armies, as well as the actual order of battle of each as applicable.

Each unit is represented by a unit entry block. The entries contain a host of information that is standardized in its presentation as far as possible. Each entry includes the unit title and type, the headquarters 

to which the unit was assigned, the geographical area to which the unit was allotted (if National Guard or 

Unit status as of 2001

Organized Reserve), the unit’s headquarters location, the unit’s physical location (or the unit’s headquarters 

location if dispersed) on 7 December 1941, a unit service narrative, the unit’s organization day, the unit’s 

status as of 2001, and a chronological listing of the unit’s commanding officers. Depending on the type of 

unit, additional information may include a listing of subordinate units and their years of assignment; “snapshot” orders of battle for divisions, corps, and armies for selected years; and the subordinate components 

of nonstandard units such as harbor defense commands. Also included in this work are the headquarters, a 

unit service narrative, commanders, and a “Major posts, camps, stations, airfields, and National Guard and 

Organized Reserve training facilities” section for each of the nine corps areas and three overseas departments. Though these were not tactical headquarters in the traditional sense, their importance to this period, 

and to this project, were such that I felt compelled to add their information.

Unit Title and Type

The unit title, in most cases, is the designation by which the unit was known for most of the 1919–41 

period. In some cases, most notably the Air Service/Air Corps units, several unit titles followed by dates are 

given due to numerous redesignations.

Parentheticals

Titles are often followed by parenthetical information. Typically, the first of these will be the unit type 

or weapon, such as (Antiaircraft) or (75-mm G). These designations will always be in boldface type. The 

notation (C) will follow some units. This indicates the unit was designated as a “Colored” unit and manned 

by African American personnel. The term “Colored” and the designation (C) were the standard usage of the 

period in mobilization documents and elsewhere and are used here for historical purposes. These designations too will always be in boldface type. Some units held the same designation at different times, but are 

not the same organization. These titles will be followed by a Roman numeral in parentheses, e.g., (I), (II), 

etc., to clearly differentiate the separate units. These designations will always be in standard type. The final 

example of parenthetical information is the major headquarters to which the unit was assigned, for example: 

(1st Division). This is typically the brigade, division, corps, or army to which the unit was assigned. For 

National Guard units, these reflect planned mobilization assignments for wartime and do not necessarily 

reflect actual peacetime command and control relationships. In some cases, again most often Air Service/

Air Corps units, the organization was assigned to several different headquarters from 1919 to 1941. In those 

cases, I have attempted to designate that headquarters to which the unit was assigned for the longest period 

or, in some instances, the headquarters to which it was assigned in the initial mobilization plans of 1921–23. 

Admittedly, there are a few instances where these two examples will not apply, but in each of these exceptional cases, the rationale was different and it is not feasible to explain every reason. The headquarters 

designations will also be in standard type.

Component and Geographic Allotment

National Guard and Organized Reserve units are identified in this section of the unit entry. The state 

or states of allotment are also identified. In some cases, the unit was allotted for organization to more than 

one state. In those instances, the states of allotment will be identified with the conjunction “and” as such: 

Alabama, Mississippi, and Louisiana National Guard. Typically, the state to which the headquarters was 

allotted will appear first. In other cases, usually Organized Reserve units, the organization was withdrawn 

from allotment to one state or geographical area, and reallotted to another. In those instances, the initial 

state or states of allotment and the follow-on state or states will be differentiated with a slash “/”, indicating the first, second, etc., areas of allotment as such: Organized Reserve Missouri and Kansas/South 

Dakota. In some cases for National Guard or Organized Reserve units, an organization was constituted but 

never allotted to a given state. In those instances, only the component (i.e., National Guard or Organized 

Reserve) is listed. Regular Army units that were generally in an inactive status between 1921 and 1939 

are shown as Regular Army Inactive (RAI). The vast majority of RAI units were organized with Reserve 

personnel during this period and thus are differentiated in this manner from Organized Reserve units and 

active Regular Army units. Many Organized Reserve units were withdrawn from the Reserve and allotted 
vii

to the Regular Army between 1927 and 1940. These units are all listed herein as Organized Reserve units 

as that is the component in which they were originally allotted. Active Regular Army units below division 

level and which headquarters were active for the majority of 1919 to 1941 will have no component listed.

Headquarters Location

The city or post and state or overseas location where the unit’s headquarters was physically and permanently located, roughly between January 1919 and 7 December 1941, is listed here. Generally speaking, 

temporary locations are not included unless the absence from the permanent location was for 6 months or 

longer. The location and relocation dates for Regular Army and National Guard units are generally accurate, 

having been determined from unit data cards for the Regular Army and state annual or biennial reports and 

various other documents for National Guard units. While the majority of the initial organization dates and 

locations for Organized Reserve (O.R.) units are generally accurate, the relocation dates were somewhat 

problematic for these units. The primary document used to determine O.R. headquarters locations are 3”x5” 

index cards located at the Center of Military History at Fort McNair in Washington, DC. These cards were 

the methodology by which the Army tracked O.R. units in the interwar period. They usually (though not 

always) contain dates and headquarters location for the relocation of the units, but the relocation dates 

themselves are often that of the actual document that notified the individual who kept the cards rather than 

the actual date of the relocation. The date provided on the index card has typically been used as the date of 

relocation in the absence of the actual date. Those dates, however, while generally accurate, can be as much 

as a year off. In those instances where the actual relocation date has been located in other kinds of documents, the actual date has been used.

Unit Service Narrative

The service narrative generally provides an overview of the unit’s permanent changes of station, assignment and reassignment to major commands, allotment to and withdrawal from component (Regular Army 

[R.A.], National Guard [N.G.], O.R.), allotment to corps area or overseas department, initial organization 

date and location, training activities and locations, activation and inactivation, and the location of the unit 

(or of the unit headquarters if the unit was dispersed) on 7 December 1941. Special events and activities, 

awards, and deployments are also covered. For R.A. units, support to the Civilian Conservation Corps and 

training support to O.R. units are covered. For N.G. units, callups for state emergencies of battalion-size 

or larger, dates of Federal recognition, dates of induction into Federal service, summer training camp locations, and mobilization training stations are covered. For O.R. units, locations for Inactive Training Period 

meetings, summer training camp locations, mobilization training stations, and Reserve Officers’ Training 

Corps (ROTC) feeder units are covered. Regular Army Inactive (RAI) units are covered similarly to O.R. 

units with the addition of information on Active Associate units and affiliation with ROTC units. Dates 

provided for unit movements are generally the dates of arrival at the new location by the unit headquarters, 

unless specifically given as a departure date from the losing duty station. Subordinate elements of the unit 

may have arrived before or after that date.

Organization Day

The War Department’s General Order #24, dated 10 June 1922, established the concept of “Organization 

Day” (sometimes referred to as “Regimental Day”) for US Army units. The Organization Day was not necessarily the date on which the unit was organized. It could also be a special date in its history such as its baptism of fire in combat. In instances where an Organization Day had been adopted, the unit’s chosen date for 

Organization Day, an explanation of the date’s significance, and the date of adoption are given, if known.

Status

The unit’s status (active, inactive, disbanded, etc.) and designation as of 2001 is given if known.

Events

The numbers represent events of significance in which the unit participated between 1919 and 1941. 

The details of each event number are located in appendix B.
viii

Commanders

Where known, the unit’s commanders and their inclusive dates of command are provided for regimentsize units and above, and selected battalion-size units. The dates of command are for the period 1 January 

1919 to 7 December 1941, or the end date of command for the last pre-World War II commander, whichever is later. For infantry, cavalry, field artillery, coast artillery, and engineer regiments, the commanders 

for the World War I period are also provided if known, because those commander lists were not previously 

provided in the Center of Military History’s Order of Battle of the United States Land Forces in the World 

War. For some N.G. units, the commanders will have a state abbreviation in parentheses following their 

name (e.g., (GA) for the state of Georgia) in those instances where the unit was a multistate organization 

to identify from which state the commander was assigned. If the commander of a N.G. or O.R. unit was an 

R.A. officer, the name will be followed by the abbreviation (R.A.). If the commander of a N.G. or R.A. unit 

was an O.R. officer, the name will be followed by the abbreviation (O.R.). If the name is not followed by 

an abbreviation, the commander is of the component or state to which the unit headquarters was allotted. If 

a commander is not known for a given period, the entry “Unknown” and the inclusive dates (at least month 

and year) are provided. In some instances, especially for O.R. units, the inclusive dates for a given commander are not known. In those cases, the entry “ao” (for “as of”) followed by a month and year indicates 

the earliest or latest date known for that commander to be in command of the unit indicated. The example 

below indicates that Colonel William J. Smith was known to be in command from at least July 1937 to at 

least April 1940.

Example: Col. William J. Smith ao July 1937–ao April 1940

Additionally, a single asterisk (*) beside a commander’s name indicates he was an R.A. officer in 

command of an RAI unit. Two asterisks (**) indicates a Reserve officer who was in command of an RAI 

unit. Note that relatively few O.R. brigades and no RAI brigades were assigned a brigadier general as 

commanding general. These headquarters functioned as such on few occasions, usually at a command post 

exercise or occasionally during annual training. The brigade was strictly a tactical command during this 

period and exercised no administrative duties or responsibilities. Those duties were performed at the division and regimental levels. For that reason, O.R. and RAI brigades were generally “commanded” by majors 

or lieutenant colonels whose duties were primarily limited to planning, conducting, or supervising training 

in the brigade headquarters during the inactive training period. More often than not, personnel assigned to 

brigade headquarters simply conducted their inactive training with one of the subordinate regiments. At 

summer training, the senior regimental commander often served as the brigade commander when the brigade headquarters was intended to function as such. When assignment of Reserve officers to RAI regiments 

began in 1926, only a single reserve major (later changed to a lieutenant colonel) was authorized as the 

commander though the regiment could acquire its full quota of captains and lieutenants from the officer’s 

Reserve Corps. In 1927, the command of these regiments was, in many cases, passed to selected Active 

Duty R.A. colonels and lieutenant colonels who, for the most part, were the professors of Military Science 

and Tactics at the college or university with which the RAI unit was affiliated. This practice seems to have 

effectively ended on 1 October 1933, though in some instances it was ended earlier, after which command 

was exercised by the senior Reserve officer assigned. Most units not affiliated with an educational institution were commanded by Reserve officers, though in a few cases they were commanded by R.A. officers 

who were assigned as an additional duty. This practice also seems to have ended on 1 October 1933. In 

many instances, brigades and regiments were commanded by captains and even lieutenants. Those organizations seem to have served more as Reserve pool units for mobilization assignment purposes than actual 

functional units. This was usually because the assigned personnel were geographically dispersed so as to 

prevent regular assembly for inactive training periods. Nonetheless, the senior officer assigned acted as the 

commanding officer during summer training unless a higher ranking officer was temporarily attached to 

assume command for the camp period.

Example Major Command Unit Entry (divisions, corps, armies)

Major command unit entries generally follow the same pattern as those for smaller unit entries with the 

exceptions detailed below.

39th DIVISION “Delta Division” Louisiana, Mississippi, Alabama, Florida,

 and Arkansas National Guard

HQ—Not organized, 1921–23

The 39th Division headquarters arrived at Newport News, VA, aboard the S.S. Matoika on 31 

December 1918 after 4 months of overseas service and was demobilized 23 January 1919 at 

Camp Beauregard, LA. In accordance with the National Defense Act of 1920, the division was 

allotted to the states of Louisiana, Alabama, Mississippi, Florida, and Arkansas and assigned 

to the IV Corps in 1921. The division’s designated mobilization training station was Camp 

McClellan, AL. The division headquarters was not reorganized before the adjutants general of 

the several states from which the division was drawn petitioned the War Department to change 

the designation of the division to be formed as the 31st Division as that was the organization 

in which most of the states’ units served in World War I. The request was approved and the 

subordinate elements assigned to the 39th Division were withdrawn and assigned to the 31st 

Division, less the Arkansas elements, effective 1 July 1923.

Nickname

Many divisions adopted nicknames in the World War I period or, in a few cases, the nickname was adopted 

after the division was constituted or reconstituted in 1921. The nicknames are shown as illustrated.

Component and Geographic Allotment

For corps and armies, only the state to which the headquarters was allotted are listed. For divisions, 

every state that was allotted a unit in the division’s order of battle is listed. The state to which the headquarters was originally allotted and organized will be listed first.

Organization/Order of Battle

Each division, corps, and field army has one or two “snapshot” orders of battle provided to illustrate 

how the command was organized at the time indicated. The 1939 order of battle provided for the R.A.’s 

1st through 9th Divisions represent those divisions’ final organization before the change to the “triangular” tables of organization in October 1939. Unit designations in italics indicate an inactive unit or a “not 

organized” or “not initiated” unit. Unit headquarters locations in italics represent the state of allotment 

for National Guard Inactive (NGI) units and the corps area of allotment for RAI and Organized Reserve 

Inactive (ORI) units. Partially active units (i.e., the headquarters was inactive, but some subordinate elements were active) are also shown in italics. For partially active units, the unit headquarters mobilization 

station/post is also shown in italics.

Division Commanders and Chiefs of Staff

Note that about half of the O.R. divisions actually had at least one general officer assigned as division 

commander sometime during this period, and none had a general assigned for the entire period. In most 

cases, one of the R.A. brigade commanders in the corps area was assigned as the commanding general 

of one of the three O.R. divisions as an additional duty. This practice seems to have been most widely 

used in the Second, Fourth, Fifth, and Seventh Corps Areas. In some cases, the corps area commander 

assigned that duty to himself. In two instances, those of the 77th and 95th Divisions, Reserve divisions were 

actually commanded by a Reserve officer. Generally speaking, the division’s chief of staff exercised routine 

command in the name of the corps area commander or the assigned division commander. Thus, the names 

of the R.A. chiefs of staff assigned to O.R. divisions have been included in this Order of Battle.

Terminology and Abbreviations

The military and ethnic terminology and abbreviations used in this work are those that were used from 

1919 to 1941; therefore, at the beginning of each volume is a Key to Abbreviations. See Appendix A, 

“Glossary of Terms,” for definitions of the terminology used in this Order of Battle.

The National Guard 

The N.G. poses several problems in preparing a work such as this because the rules by which the 

Center of Military History (and the states themselves) trace each unit’s lineage do not always mirror those 

for the R.A. and O.R./US Army Reserve. For example, when a unit in the O.R. was relocated from one 

community to another, the unit retained its history and designation. In the case of the N.G., however, when 

a unit designation was relocated to a unit in another community, the history of the unit was retained in the 

organization located in the first community. Also, if a unit was demobilized (i.e., disbanded) in one community, and then in another community a unit is organized with the same designation, there was, in theory, 

no relation between the two units other than the fact that they happened to have shared the same designation. For example, the 120th Ammunition Train was organized at Bristow, OK, in May 1923. The unit in 

Bristow was disbanded in May 1924. A new 120th Ammunition Train was organized at Sperry, OK, in June 

1924 and later reorganized as Headquarters Battery, 160th Field Artillery in June 1926. Another new 120th 

Ammunition Train was organized at Haskell, OK, also in June 1926, and later reorganized as Battery B, 
xi

160th Field Artillery in January 1927. In theory, there were three different organizations with the designation “120th Ammunition Train” and as such, each should merit a separate Unit Entry in this Order of Battle. 

To complicate matters, regimental, brigade, and division headquarters appear not to have been considered 

state- or community-specific units. For example, the Headquarters, 108th Cavalry at New Orleans, LA, was 

withdrawn from the state of Louisiana on 15 March 1929 and allotted to the state of Georgia and reorganized at Hinesville, GA. There appears to have been no loss of identity or history in the transfer of that unit 

designation between states, much less between communities in the same state. It is the same unit with the 

same lineage. Additionally, the Center of Military History does not consider N.G. units “constituted,” even 

though the Federal designations of those units were clearly “placed on the rolls of the army” (this is especially pertinent since the vast majority of N.G. units used Federal designations and not state designations 

during the period) and allotted to the various states in 1920–21 in accordance with the guidelines laid out 

in the 1920 amendment to the National Defense Act of 1916. The methodology appears to assume that the 

designation does not exist (at least on the rolls of the Army) until the day the unit is organized and federally 

recognized, even though letters and memorandums allotting the unit designation to a state, mobilization 

plans, and numerous other documents clearly refer to the existence of the unit designation before it was 

actually organized. In light of these pre-existing designations, for the purposes of this Order of Battle, I 

have chosen to consider the designation of N.G. units to have been constituted in the same manner as R.A. 

and O.R. units (i.e., when the designation of a unit was placed on the rolls of the Army). Therefore, those 

units that have a clearly differentiated identity (in other words, separate battalions, regiments, divisions, 

etc.) are treated as one and the same organization in the Unit Entries. Only in rare instances are two (or 

more) N.G. units with the same designation treated as separate and distinctly different organizations. The 

Unit Entries for these units generally makes the purpose for differentiation self-evident.

Chapter 28

 Air Service and Air Corps Major Commands

Aircraft of the 1st Air Division assembled at March Field, CA, for maneuvers, May 1933.

Initially, the major commands for the Air Service consisted of the General Headquarters Air Service 

(redesignated as the General Headquarters Aviation in 1928), air divisions, air brigades, and wings. The 

latter three, with one exception, were intended to provide the subordinate command structure for the 

General Headquarters Air Service. The wing, the one exception, could also be a component of an army air 

service as well. 

The General Headquarters Air Service was intended to be the command and control headquarters for all 

air service units in the General Headquarters Reserve. This included all air service units less those assigned 

to army, corps, and division air service headquarters. This command eventually evolved into the General 

Headquarters Air Force which was partially organized in 1933 and redesignated as the Air Force Combat 

Command in 1941.

Air divisions were composed of two or more air brigades. These commands were tailored for specific 

missions such as aerial defense of a given geographic area and thus had no standardized organization. Five 

air divisions were constituted in the Organized Reserve in the interwar period. One division, designated 

as the “1st Air Division,” was organized provisionally for the 1931 air corps maneuvers that took place 

across the eastern United States, but was discontinued after only two weeks of active service. The actual 

1st Air Division, constituted in 1921, for some reason was demobilized in 1933, then another of the same 

designation immediately constituted. The new division was initiated in 1935 only for a short period, but 

never functioned as an actual headquarters. Coast Artillery Journal
1236

Air brigades were composed of two or more wings plus additional air and ground assets as required 

for a specific mission. Air brigades were generally mission- or equipment-specific such as bombardment, 

airship, balloon, and training or school brigades. Twelve air brigades were constituted or organized in the 

Army during this period—three in the Regular Army and nine in the Organized Reserve. Two brigades (both 

designated “1st”) were active during various periods in the interwar period. The first was Billy Mitchell’s 

1st Air Brigade that won some notoriety for sinking obsolete battleships off the coast of Virginia in 1921. 

Several of the Reserve brigades were initiated as well, but all were inactivated by 1933.

Wings consisted of two or more groups plus additional air and ground assets as required for the mission. 

Wings were designated as airship, attack, balloon, bombardment, pursuit, or transport, though in the case 

of heavier-than-air wings (i.e., fixed wing aircraft), the wing was at times composed of a mixture of groups 

which created a composite wing. A total of fifty-eight wings of various types were constituted between 1919 

and 1941. Twenty-three of these wings saw active service in this period, most of them only briefly prior to 

the attack on Pearl Harbor. Many of the others were initiated at some point as Reserve units, but none of 

those wings functioned as actual headquarters.

Chapter 29

Headquarters, Air Service and Aviation

A Curtiss O-11 from the 101st Observation Squadron undergoes inspection circa 1928.

Headquarters, Air Service (redesignated Headquarters, Aviation in 1928) were authorized at three 

command levels: army, corps, and division. These commands provided command and control for assigned 

or attached army air service and air corps units.

Organization 

The army air service possessed all assets required for conducting tactical operations in support of the 

field army. The service’s mission was to achieve air supremacy over the field army’s airspace to allow 

the service’s attack squadrons the freedom to attack enemy formations and key installations as well as 

cooperate with ground units as they maneuvered to engage enemy forces. The army air service consisted of 

a headquarters and an attack wing of one attack group and two pursuit groups. Separate from the wing, but 

part of the air service, were an observation group, a communications section, three airdrome companies, 

an ordnance maintenance company, and a headquarters squadron. All six of the field army air service 

headquarters were constituted in the Organized Reserve and initiated. All six were inactive by 1929. 

The corps air service possessed assets required for selected tactical operations in support of the 

corps. The service performed visual and photographic reconnaissance missions, command observation 

missions, spotting for the adjustment of artillery fire, and maintained contact with wide-spread infantry 

and supporting cavalry formations. The service could supplement divisions for various operations and 

attach balloon companies to both the corps and division artillery to perform spotting services. The corps 

air service consisted of a headquarters, one observation group, and one balloon group. Six of the corps 

air service headquarters were constituted in the National Guard and twelve in the Organized Reserve. 

None of the National Guard corps air service headquarters were ever organized; all twelve of those in the USAF photo
1262

Organized Reserve were initiated during 1921-22. As with the army level headquarters, all corps air service 

headquarters were inactivated by 1929. 

The division air service possessed assets required for conducting selected tactical operations in support 

of the division and performed missions similar to those of the corps air service. The service consisted of a 

headquarters, and observation squadron, an air intelligence section, and a photographic section. A division 

air service was provided for each of the National Guard and Organized Reserve infantry divisions in 

1921. For some reason, the Regular Army divisions were not authorized an air service until 1923. Cavalry 

divisions were authorized a division air service in 1927, but the units were eliminated from all types of 

divisions less than two years later in 1929. All division air service headquarters were demobilized that year 

and their subordinate elements were reassigned to corps observation groups.

None of the air service headquarters at army and corps level were functional units, and therefore, 

none ever functioned as actual headquarters. The divisional air service headquarters—RA, NG, and 

OR—were almost always collocated with the observation squadrons that were assigned to them. In fact, 

more often than not, the observation squadron commander also functioned as the air service commander 

(though that arrangement was not intended for wartime operations). Therefore, most RA and NG division 

air services did function as command headquarters, though as a command level, they often seemed to be 

indistinguishable from their subordinate observation squadron due to the dual command functions of the 

squadron commander. The OR headquarters were functional only as far as their participation in the Inactive 

Training Period activities and summer camps. They did not exercise command functions as a separate 

headquarters except perhaps during CPXs.

Training

Since none of the army and corps level air service headquarters were functional units, the Inactive 

Training Period activities of the personnel assigned to those units were generally limited to training 

attendance with other units, troop schools, or correspondence courses. None of these units attended camps 

as organizations. 

The Regular Army division air services generally supported the training of their respective divisions. 

They performed reconnaissance missions for the ground units and often played the role of enemy attack and 

observation aircraft to help train the ground units in reacting to aircraft attacks and camouflaging against 

aerial observation. These units also participated in many of the various air corps maneuvers in the 1920s 

and 30s as well. Additionally, Regular Army units assisted the summer training of various RAI and OR air 

service units as well.

The National Guard division air service units were also frequently integrated into their division’s 

summer training and performed a number of other types of training missions as well. In addition to normal 

flight training operations, National Guard air services were employed in search and rescue missions, forest 

fire patrols, aerial photography and mapping missions, and aerial observation support to assist field and 

coast artillery organizations during live-fire exercises.

Since most OR division air service headquarters did not function as separate and distinct units from 

their subordinate observation squadrons, they did not have training activities separate from their subordinate 

units. However, because many of the divisional observation squadrons were some of the best-equipped 

and most active flying units in the OR, the few personnel assigned to an air service headquarters benefited 

from the training held by those squadrons during the Inactive Training Period. The headquarters typically 

attended summer training with the squadron as well.

Chapter 30

 Groups

YB-17s of the 2nd Bombardment Group intercept the S.S. Rex at sea, 12 May 1938.

Groups provided command and control for assigned or attached army air service and air corps units.

Organization 

There were nine types of group headquarters in the interwar era—six heavier than air (HTA), two 

lighter than air (LTA), and one special group. The HTA groups included attack, bombardment, observation 

(some later Redesignated as reconnaissance groups), pursuit, transport, and composite units. The LTA 

groups included airship and balloon organizations. The special headquarters was the school group, which 

could be HTA, LTA, or non-flying organizations. Many of these group headquarters underwent one or more 

conversions or redesignations so it is difficult to illustrate how many types of groups were in each category. 

The following table, however, shows the allotment of those types of units as they were originally organized 

as of 1921 or as originally constituted and in the component to which they were originally allotted. The 

table includes only those units organized or constituted prior to December 1939 in the case of Regular Army 

units and as of December 1940 for National Guard and Organized Reserve units. USAF Photo

With two exceptions, all HTA groups consisted of four squadrons, one service squadron (designated as 

an “air park” until 1923), and a photo section. The pursuit and transportation groups were the exceptions and 

neither had a photo section. The two LTA groups were similarly organized except that they were composed 

originally of four airship or balloon companies. The companies were redesignated as squadrons in 1933. As 

their name suggests, composite groups consisted of a mixture of squadrons. Typically, a composite group 

would have at least one bombardment, one observation, one pursuit, and a service squadron each. The mix 

might not have included one or more of the squadrons, but would always include the service squadron. 

School groups were also generally composed of four school squadrons, but could consist of more or less 

as well. A school group could also be either a flying or non-flying unit depending on the mission it was 

assigned. The group’s basic structure held steady until 1936 when the service squadrons were eliminated 

from the organizational scheme. The structure remained the same thereafter until World War II.

None of the National Guard balloon groups were ever organized and all were demobilized in 1927. 

Additionally, none of the Regular Army Inactive or Organized Reserve groups were functional units and 

therefore did not function as headquarters. At the time of Pearl Harbor, all active air corps groups were 

Regular Army organizations and none of the OR groups were activated for World War II service.

Training

Given the nature of the flying service, air corps units tended to be very active in terms of actual training. 

This was particularly true of the Regular Army. These groups not only participated in many of the ground 

units’ training exercises, they conducted many of their own maneuvers as well. Particularly after 1929, many 

of these groups participated in rather large-scale air maneuvers two or three times a year. The groups also 

participated in a number of demonstrations and events that were primarily designed for public relations both 

nationally and internationally. For example, contingents of the 2nd Bombardment Group flew to Argentina 

in 1937 on a “Goodwill Flight” for the purposes of creating better relations with South American countries.

Since OR group headquarters were pool units, they did not conduct training activities during the Inactive 

Training Period. The headquarters personnel participated in the training activities of their subordinate 

squadrons or with other units. They also typically attended summer training as individuals or with one of 

the group’s squadrons that was ordered to camp.

Squadrons, Heavier Than Air

Curtiss P-6 Hawks of the 17th Pursuit Squadron over Selfridge Field, MI.

Heavier Than Air (HTA) squadrons provided direct or indirect support to the ground gaining arms. This 

could be as direct as attack and observation missions against the enemy’s front forces, or as indirect as 

the bombing of the enemy’s industries and infrastructure in order to cripple that nation’s war-making 

capabilities. Some also provided specialized support to include aircraft maintenance and testing, personnel 

and equipment transportation, training, and aerial photography. USAF Photo
1360

Organization

There were nine types of HTA squadrons in the interwar era. Four of these squadrons—attack, 

bombardment, observation (some later redesignated as reconnaissance squadrons) and pursuit—were to 

be employed in direct combat roles. The remaining five—transport, photographic, service, school, and 

headquarters squadrons—were support organizations that performed a variety of missions and functions. 

Like the group headquarters, many of these squadrons experienced one or more reorganizations and/

or redesignations so it is difficult to illustrate how many types of squadrons were in each category. The 

following table, however, shows the allotment of squadron types as they were originally organized as of 

1921 or as originally constituted and in the component to which they were originally allotted during 1921-

40. The table includes only those units organized or constituted prior to December 1939 in the case of 

Regular Army units and as of December 1940 for National Guard and Organized Reserve units.

Units Organized or Constituted.

* There were a number of OR school squadrons constituted in the Organized Reserve but were apparently nonflying organizations. They are listed in Chapter 33.

Squadron structure varied by type, but in general, it consisted of two to three flights, an operations 

section, armament section, communications section, and an engineering section. Depending on the type 

of squadron, it might also include a photo section, a supply section, and a transportation section. Attack, 

bombardment, pursuit, and transport squadrons were typically assigned four squadrons to a like group 

(i.e., pursuit squadrons in a pursuit group). They could also be assigned to a composite group, but that 

group usually consisted of only one bombardment, one observation, and one pursuit squadron each. Service 

squadrons were also assigned one each to a group regardless of type. Additionally, a single observation 

squadron could be assigned to a division air service, or in some cases were unassigned, or attached to 

bombardment groups. School squadrons were assigned to school groups in varying numbers. The single 

photographic squadron was an asset of the Office, Chief of the Air Corps and performed special missions 

for that command. Headquarters squadrons were assigned one to each field army air service and performed 

the typical support functions associated with such organizations (administration, supply, etc.)

The T/O structure of most of these squadrons remained relatively constant throughout the interwar 

period. However, some were changed or eliminated. Most headquarters squadrons, for example, were 

reorganized and redesignated as air depot headquarters in 1933. Service squadrons were either demobilized 

or consolidated with existing group headquarters between 1936 and 1938. Some observation squadrons 

were redesignated as reconnaissance squadrons in 1936 and some in 1939. Many squadrons were also 

reorganized and redesignated from one type of squadron to another. Most squadrons’ group assignments 

remained relatively constant during this time, but a sizable number were relieved from one group and 

assigned to another. This was especially true for the Regular Army as the number of squadrons and groups 

brought into active service continued to increase during the interwar years. 

Of the sixty-one National Guard squadrons constituted during this time, only thirty-three were ever 

organized. All of the organized units were observation squadrons and none of the eight service squadrons 

allotted to the Guard were ever organized. Of the organized squadrons, all but four entered active duty 

during 1940-41

As was the norm for most types of Army units in this period, the majority of air corps squadrons were 

OR organizations. Over 320 of the nearly 570 HTA squadrons were Reserve units. The majority of those 

units were organized at some point in the interwar period, but about thirty were never initiated. Only three 

of the OR squadrons are known to have served in World War II (482nd, 484th, and 485th Bombardment 

Squadrons), and then only by being reconstituted and consolidated with an existing new organization.

Training

The Regular Army squadrons were very active organizations when compared to the rest of the Army 

between the wars. Of course, part of that activity was in the nature of such organizations. Pilots had to 

maintain proficiency in perishable flight and warfighting skills and support personnel had to ensure that the 

squadron’s planes were ready for training, or in the case of overseas squadrons, ready for combat. These 

squadrons participated in a host of training exercises, both with the Army’s ground units and with other air 

corps organizations. These training events included maneuver training with infantry and cavalry units from 

battalion to division-level (and later to corps and field army-level), antiaircraft exercises, coast and field 

artillery live-fire exercises, aerial photography and mapping missions, and exercises with naval sea and air 

units as well. Squadrons also participated in their own training exercises to maintain proficiency in their 

primary missions, whether that was bombing exercises for attack and bombardment units, resupply and air 

movement exercises for transportation units, or aerial gunnery and targeting exercises for pursuit units. In 

addition, these squadrons often supported the summer training of OR squadrons. 

Most of the Regular Army Inactive units that were organized with Reserve personnel were functional 

units. This was primarily because these units were generally located on or near Army air fields or Organized 

Reserve airdromes and had easy access to army aircraft. Many of these locations also happened to be 

located near cities that were air hubs for major U.S. airlines. This was significant because many airline 

pilots were also Reserve officers. 

All of the organized National Guard observation squadrons had the luxury of being situated at civilian 

or former military airfields on which the squadrons possessed two or three hangers and perhaps a few 

auxiliary buildings. The units were typically assigned about six aircraft for flight training and proficiency 

which were parked and maintained at the Guard unit’s facilities. In addition to normal flight training 

operations, National Guard observation squadrons were employed in a large number of training and other 

missions such as search and rescue, tow-target and spotter flights for the coast and field artillery, photo 

missions, forest fire patrols, and any number of others. Some of these missions were performed during the 

unit’s summer training and others were performed during the Inactive Training Period. All of these kinds of 

duties, however, helped make the NG observation squadrons some of the best-trained organizations in the 

Reserve components.

The vast number of Organized Reserve squadrons were a mixed bag. Many were functional units. 

Like the RAI units, the most active were those squadrons that were lucky enough to be based at an Army 

airfield or at a Reserve airdrome. Reserve squadrons that were located at or near Regular Army airfields 

were authorized the use of the aircraft from RA squadrons to maintain flying proficiency. The Organized 

Reserve squadrons in these situations generally held their Inactive Training Period meetings and summer 

training at those airfields as well. A small number of Reserve units were assigned Army aircraft that were 

based at their local airports.These units were typically allocated only about four to six planes and they were 

usually a mixture of types, mostly trainers and obsolete observation planes. There were only a handful 

of these units, however; usually only two or three per corps area. Other squadrons that were collocated 

at the same airfield were lucky as well because the pilots of those squadrons could freely use the owning 

squadron’s aircraft based at the airport. Since there were few Reserve enlisted personnel in these squadrons, 

the maintenance of these aircraft was conducted by a small RA air corps detachment assigned to the field or 

the Reserve airdrome. Some Organized Reserve squadrons were functional units but did not have the luxury 

of having assigned planes or Regular Army aircraft based nearby. These units were functional only because 

of the assigned personnel made efforts to conduct training meetings with the sparse resources at hand, 

which occasionally included privately-owned aircraft. These units’ Regular Army instructors were also 

able to arrange for Army aircraft to be flown into a local airfield for weekend training events, but this was 

uncommon. A sizable number of Organized Reserve squadrons were pool units made of up geographically 

dispersed members. These units were occasionally ordered to summer training, but usually their personnel 

attended camps as individuals attached to other units.

Companies and Squadrons, Lighter Than Air

Airship C-41 from the 19th Airship Squadron at Virginia Beach, VA in 1930.

Lighter Than Air (LTA) squadrons provided aerial reconnaissance and observation support to the arms.

Organization

There were four types of LTA companies in the interwar US Army force structure. These included 

airship companies, balloon companies, airship service companies, and balloon service companies. There 

were a number of these companies that were designated as school and air depot units, but those designations 

appear to have referred to mobilization assignments and did not indicate a material difference in their T/O 

from any companies of their type. The following table shows the allotment of companies and squadrons 

by type as they were originally organized as of 1921 (in the case of Regular Army units) or as originally 

constituted and in the component to which they were originally allotted in the interwar period.

The story of the US Army’s experience with LTA operations is one of a technology that seemed to have 

great potential coming out of the Great War, but could not realize that potential when competing against the 

reality of peacetime military budgets and the onward march of its heavier than air competition. Proponents 

in the air service envisioned many ways that LTA organizations could contribute to the Army’s wartime 

missions. From coast defense operations to what amounted to the strategic mission of terror bombing 

civilian populations deep in the enemy’s interior, a la Giulio Douhet, LTA enthusiasts had great plans for 

the airship and balloon in warfare. The plans of these proponents soon ran up against battles in the Army 

budgeting process as the Congress slashed funding to the Army. Army planners and leaders, while agreeing 

that LTA organizations and capabilities were needed in the force structure, believed that HTA technologies 

and organizations held much greater potential for future warfare. Thus, the lion’s share of money went to 

funding the air service’s HTA arm.

Still, planning for LTA capabilities went forward. In 1920 there were thirty-two World War I-era 

balloon companies still on active duty. That year, the air service estimated that it would only need ten active 

balloon companies for the purposes of coast defense and patrolling duties on the Mexican border. To support 

these plans, the air service began construction of balloon sheds near various harbor defense locations on the 

east and west coasts, as well as several along the Mexican border. Additionally, several balloon companies 

began a series of tests and experiments working with coast artillery batteries in California, Washington, 

and Hawaii. Within two years, however, twenty-two of these companies were demobilized or inactivated, 

another eight reorganized as airship companies, and the remaining two were reorganized as LTA school 

units, one of which was also demobilized a short time later. By 1922 no balloon companies were on active 

duty. By then the Army’s active LTA force consisted only of one airship group headquarters, four airship 

companies, and one airship service squadron.

Over the next nineteen years, the active LTA force would undergo a number of activations, inactivations, 

and demobilizations. In 1927 several new balloon companies were constituted in the Regular Army to 

replace some of those companies that were demobilized in 1922. Several of those companies were then 

demobilized several years later in 1933 as the Army continued to struggle with mobilization plans and 

force structure. By 1933, there were only two balloon squadrons, two airship squadrons, and one airship 

service squadron on active duty, though there were several others that were active as RAI units. In 1935, 

the one remaining service squadron was inactivated and two years later, the Army agreed to transfer the 

airship mission to the Navy. At that time, the two remaining airship squadrons were consolidated with 

other air corps units and all airships and related equipment was handed over to the Navy. Concurrently, the 

Army organized a third balloon squadron from one of the former airship organizations. For the next several 

years these three squadrons supported the training of the field artillery and coast artillery schools as well as 

several harbor defense commands. 

In 1940, the 3rd Balloon Squadron at Camp Davis, North Carolina, was reorganized as a barrage balloon 

organization for testing with coast artillery antiaircraft units. A dozen or so barrage balloon squadrons were 

contemplated for mobilization but at the time it was not clear whether the units would come under air corps 

or coast artillery control. Nevertheless, the 3rdSquadron set about helping to validate the concept and, once 

the decision was made to put the units under the coast artillery, it formed the basis of the training center for 

the new barrage balloon units. 

During the Louisiana maneuvers in 1941, the 1st Balloon Squadron encountered a new competitor. 

Several Piper Cub aircraft were used for spotting artillery fire and they proved to be very successful. The 

writing was now on the wall for the army’s LTA air arm. Though the three remaining squadrons were still 

on active duty at the time of Pearl Harbor, all soon went the way of the horse cavalry. With the inactivation 

of all three squadrons in February 1942, the air corps’ experiments with lighter than air platforms passed 

into history.
1557

The structure for balloon and airship companies were almost identical. Both consisted of six sections: 

headquarters, communications, transportation, supply, maneuvering, and armament. Both also possessed 

184 officers and men to support, maintain, and operate one balloon or airship. The fact that there was 

only one craft per company indicates the complexity associated with LTA aircraft. The service company 

was a simpler organization, but as large. It consisted of a headquarters and an engineering section. The 

organization of the LTA companies underwent a T/O reorganization in 1930 that authorized two aircraft 

to each type of organization. Though the T/Os for LTA squadrons were adopted in 1930, the change in 

designation did not take place until over three years later. 

Balloon companies and groups, were typically assigned to army corps to support artillery operations 

and provide battlefield observation. Companies were assigned four to a group along with one service 

company. Though a large number of balloon companies and groups in the mobilization plans were slated 

for assignment to army corps, there were also a number allotted to the General Headquarters Reserve 

and the Zone of the Interior, with the latter being mostly school troops. Airship companies along with 

one service company were also assigned four to each airship group. Most of the airship companies and 

service companies were assigned to the General Headquarters Reserve. Three airship groups, however, 

were assigned to the overseas departments. Like the balloon companies, there were a number of companies 

assigned to the Zone of the Interior as school troops. 

There were a sizable number of balloon and balloon service companies assigned to the National Guard. 

These units were mostly corps troops although one Guard balloon group was assigned to the General 

Headquarters Reserve. None of the NG units, however, were ever organized and all were demobilized in 

1927.

By far, the majority of LTA companies were OR organizations. Many of those units were initiated 

at some point in the interwar period, but substantial numbers were never assigned any personnel. Many 

others were demobilized in 1927 and 1928, and by the following year, many of those that had been initiated 

had now been inactivated. Most of those personnel appear to have been transferred to other Reserve 

organizations, but not necessarily air corps units. In 1933, a large number of additional Reserve LTA units 

were demobilized as the Army struggled to find the right mix of units. By the late 1930s, relatively few of 

the OR balloon and airship squadrons originally initiated in the early 1920s remained active. By the time 

of Pearl Harbor even fewer were functional units and none were ordered to active duty. 

Training

The Regular Army’s LTA companies and squadrons were fairly active organizations between the 

wars mainly because there were so few of them. In addition to their own training exercises to maintain 

proficiency in their primary missions, these units supported a variety of other training events to include 

maneuver training with coast and field artillery units, Billy Mitchell’s aerial bombing tests of obsolete 

battleships off the Virginia coast, and exercises with naval sea and air units. These units also frequently 

entered their balloons and airships in the annual National Balloon Race, the International Balloon Race, and 

other prestigious LTA races. In fact, a US Army balloon crew won the former race three years running from 

1926 to 1928. In addition to activities, balloon and airship companies often supported the summer training 

of Organized Reserve LTA units as well. 

All of the RAI LTA units that were organized with Reserve personnel were concentrated in the area of 

Chicago, Illinois. Given that fact the largest concentration of LTA units and the airship school was located 

only a four-hour drive away at Scott Field, that concentration seemed to make sense. For the relatively short 

period the RAI units in Chicago were functional units, those units’ personnel were largely concentrated in 

and around the city and were thus easily assembled for training. For unknown reasons, most of the units in 

Chicago were inactivated in 1932 and apparently none were ever ordered to camp as a unit.

It is unlikely that very many of the Organized Reserve LTA units were functional organizations. The 

most active were those units located at or near installations where Regular Army LTA units were based. 
1558

In those instances Regular units could make their equipment and facilities available to the Reservists to 

support their training. These examples are few, however. Most of the Reserve LTA units were typically 

located in small communities and cities too far away from active units to enjoy such benefits. Additionally, 

the Reserve companies typically consisted of only four to eight officers whose residences were often 

geographically dispersed making it difficult to frequently assemble the unit during the Inactive Training 

Period. Thus, the large majority of the Reserve organizations were most probably pool units. Moreover, 

less than thirty of these units were ever ordered to summer training as units. Generally speaking, functional 

organizations were ordered to camp as units; the personnel of pool units were usually ordered to camp as 

individuals and were attached for training to the functional units.

Chapter 33

Squadrons, Non-Flying

Formation flying over the “Taj Mahal” at Randolph Field, TX. Randolph became known as the “West Point of the Air” 

in the 1930s.

These squadrons had a variety of missions which they performed to support the operations of other 

organizations or the operation of the air corps’ training base. 

Organization

When organized in 1936, base headquarters and air base squadrons were created largely by subsuming 

existing airfield station complements (i.e., support detachments) and the service squadrons assigned to flying 

groups. The intent in creating these units was to eliminate the need for air corps groups to have an assigned 

service squadron. To whatever airfield the group traveled for training and exercises, it could now rely on 

the field’s air base squadron for the required support for its personnel and equipment. These units provided 

a wide variety of base support functions for Army airfields. Their focus was on broad generic support 

for the entire air base including non-flying activities. These base support functions included personnel 

administration, transportation, maintenance, medical, and logistics operations. The latter function included 

all classes of supply to include fuel, food services, ammunition storage and issue, and repair parts. The 

base headquarters commander was the airfield commander. His staff provided the overall supervision of 

air base support operations. The air base squadron provided the support functions as outlined above. These National Archives II
1624

units were reorganized in 1940 into headquarters and headquarters squadrons and redesignated as air base 

groups.

Airdrome companies, and later as airdrome squadrons, focused their support on airfield and flight-line 

support operations, i.e., support of flying activities. The airdrome units provided service station-type support 

to the field. This included aircraft refueling, routine maintenance and repair, calibration and adjustment of 

aircraft components, taxi control and parking of aircraft on the apron, etc. These units were usually assigned 

or attached to air depots and later to the base headquarters at the airfield where they were operating.

Repair squadrons provided higher echelons of maintenance and repair for supported groups and 

squadrons. These squadrons were typically assigned two to each air depot.

Supply squadrons provided higher echelons of logistics support for supported groups and squadrons. 

These squadrons were also usually assigned two to each air depot.

Weather squadrons provided weather data to airfield operations centers for the purposes of mission 

planning and execution. The squadrons were organized into small detachments that were deployed to a 

number of airfields within a geographical region. 

Training

The only squadrons listed in this chapter that were in active service prior to Pearl Harbor were the base 

headquarters and air base squadrons and weather squadrons, all of which were Regular Army organizations. 

Since these units performed their real-world support missions on a daily basis, one could say they were in 

training all the time.

The remaining squadrons were Regular Army Inactive or Organized Reserve units. None were in the 

National Guard. A number of the RAI units were organized with Reserve personnel, as were many of the 

OR units. None appear to have been functional units in the Inactive Training Period and only ten were 

known to have attended a summer camp as a unit. Most likely, the personnel assigned to the initiated RAI 

and OR organizations trained as individuals with other units both at camp and during the Inactive Training 

Period.

Engineer Organizations

Chapter 34

 Engineer Major Commands

Troops of the 4th Engineers construct a pontoon bridge across the Chattahoochee River at Fort Benning, GA.

There were a number of different types of major engineer commands in the interwar army, some with 

very specialized missions, others possessing a more general engineering function. All provided command 

and control for various types of engineer organizations and operations. 

Organization

The largest engineer command was the Engineer Headquarters, General Headquarters constituted 

in 1921. This command was demobilized in 1928 and replaced in 1933 by the Headquarters Engineer 

Service, General Headquarters. Both commands provided the same function—providing command and 

control of General Headquarters Reserve engineer units. The former command was an Organized Reserve 

headquarters; the latter was constituted in the Regular Amy. 

Another major command was the Engineer Headquarters, Communications Zone constituted in the 

Regular Army in 1928. The mission of this headquarters was to command and control railroad operations 

in the communications zone of a major theater of war. 

Six army engineer headquarters were constituted in the Organized Reserve in 1921. These commands 

were responsible for the improvement and construction of roads, railroads, and bridges in the army area of 

operations. Its units also provided camouflage. topographic, and water supply services to the field army. The 

army engineer service consisted of the following units:

Headquarters, Army Engineer Service

Three Engineer Regiments (General Service)

Six Engineer Battalions (Auxiliary)

The Military Engineer
1676

One Engineer Battalion (Topographic)

One Engineer Train (Water Tank)

Five Engineer Trains (Heavy Bridge)

Two Engineer Trains (Light Bridge)

One Engineer Train (Dump Truck)

One Engineer Company (Camouflage)

Of the eighteen corps engineer headquarters two were constituted in the National Guard, the remainder 

in the Organized Reserve. These commands did much of the same work for the corps as did the army 

engineers at that level, although their capabilities in most areas were far more limited. The corps engineer 

service consisted of one engineer regiment (general service) and three auxiliary engineer battalions.

Seventeen Engineer Headquarters (Railway Service) were constituted in the Army between 1921 and 

1941. Four of these were in the Regular Army, the remainder in the Organized Reserve. These headquarters’ 

mission was to provide command and control to two or more engineer railway operating battalions operating 

rail system sections within the advanced, intermediate, or base sections of the Communications Zone. 

These headquarters answered to the Engineer Headquarters, Communications Zone. 

Six Engineer Headquarters (Communications Zone Section) were constituted in the Organized Reserve 

in 1923. These headquarters’ mission was to provide command and control to engineer organizations 

operating within a designated geographical section of the advanced, intermediate, or base sections in the 

Communications Zone. These headquarters also answered to the Engineer Headquarters, Communications 

Zone. 

Training

None of these headquarters served on active duty in the interwar period, though many were organized 

in the Reserves during that period. With the exception of several RAI railway service headquarters, all 

were inactivated by 1929. None functioned as actual headquarters. These units were primarily used for 

mobilization assignments (i.e. pool units) for Organized Reserve engineer officers with professional 

engineering skills gained from their civilian employment. There’s no evidence any were functional units 

during the Inactive Training period or attended training camps, CPXs, or maneuvers as such.

Chapter 35

Engineer Regiments

Men of the 5th Engineer Regiment build an antitank log crib at Fort Belvoir, VA.

Engineer regiments provided road and trail improvement and vertical structure, battle position, 

and obstacle construction support to mobile units of the field army, corps, and division. Under extreme 

circumstances, engineers could be used as infantry.

Organization

The organization and types of engineer regiments in the post-war Army were modified and reduced 

versions of the types of units that served in World War I. Rather than the approximately ten different types 

of engineer regiments that existed during the war, there now existed only three distinct organizations: the 

divisional combat regiment, the general service regiment, and one short-lived camouflage regiment. Many 

of the functions performed by the specialized wartime regiments were now either incorporated into one of 

the new post-war engineer battalion structures, or, in a few cases, were transferred to the Chemical Warfare 

Service, Coast Artillery, or Field Artillery. The following table illustrates the allotment of the types of units 

to the various components through 1940.

The Military Engineer
1692

Engineer Regiment TOE.

The sapper regiment of the First World War evolved into the post-war divisional combat engineer 

regiment. Each division was assigned one of these regiments to provide the command with the ability to 

improve mobility corridors such as roads and trails, as well as avenues of approach toward enemy positions. 

The units provided obstacle breaching and construction services, as well as defense position improvement 

and reinforcement capabilities. Each regiment consisted of a headquarters, a headquarters and service 

company, and two sapper battalions of three companies each. 

The general service regiment was organized similarly to the combat engineers. This regiment, however, 

was substantially larger (by approximately 25 percent) and provided greater road improvement and vertical 

construction capability than the combat engineers. It could also perform some specialized functions, such 

as forestry skills, not typically present in the divisional regiment. Three GS regiments were assigned to each 

field army and one to each corps. Additionally, a significant number were assigned to the GHQR and CZ 

for employment in the rear areas or for reinforcing army, corps, or division operations. One regiment was 

assigned duties as a training unit and was slated for mobilization at Fort Belvoir, Virginia.
1693

Engineer General Service Regiment TOE.

The single camouflage regiment, the 40th Engineers, possessed an odd table of organization. It consisted 

of one battalion of three companies (companies A–C) and six separate camouflage companies (companies 

D–H). There was no regimental headquarters. The single battalion was assigned to the GHQR and each of 

the separate companies was assigned to one of the six field armies. This regiment was broken up in 1930 

when the companies were demobilized and the 1st Battalion was reorganized and redesignated as a separate 

camouflage battalion. 

The organization of the engineer regiments remained relatively constant until 1939 when the combat 

regiments of the Regular Army divisions were reorganized into battalions as part of the triangular division 

concept. The combat regiments in the National Guard and Organized Reserve divisions would not follow 

suit until early 1942. The general service regiments remained relatively unchanged although one was 

converted to an airfield construction regiment in 1940. By the time of Pearl Harbor virtually all of the RAI 

and National Guard units had been activated for duty, but none of the Reserve regiments. A handful of the 

existing Reserve regiments would eventually be activated, however, later in 1942.

Training

The annual training cycle for Regular Army engineer regiments was similar to that for other combat 

arms units (see Chapter 9, Infantry Regiments, for a general description). Since all but one of the active 

engineer regiments in the interwar period were divisional units, training events for engineer regiments 

tended to be centered on providing support to other units of their assigned division. This was particularly 

true for the three overseas regiments—the 3rd, 11th, and 14th Engineers. All three not only participated in 

the annual division and department maneuvers, they also performed various construction projects, many 

related to improving roads, trails, and battle positions to support aspects of existing defense plans. The 11th 
1694

and 14th also mapped various areas of the Canal Zone and the Philippines that were that were important to 

war plans and were previously uncharted in any geographic detail. 

The stateside regiments also participated in the exercises and maneuvers of their assigned divisions and 

reinforced brigades. These regiments, and there were only four relatively complete regiments—the 1st, 2nd, 

6th, and 13th—were also heavily taxed to support the training of the Organized Reserve, Reserve Officer 

Training Corps, and Citizens Military Training Corps during the summer. In this regard, the 1st Engineers 

supported the civilian components of multiple corps areas as did the 13th Engineers as there were no active 

Army engineer units in the First and Sixth Corps Areas. Like their overseas counterparts, the stateside units 

also performed various construction and mapping projects as well.

Most RAI engineer regiments seem to have been functional units. These units usually conducted their 

Inactive Training Period assemblies similarly to other Reserve regiments. In several instances RAI regiments 

conducted their training meetings in conjunction with other local engineer reserve units. Additionally, when 

ordered to camp, the RAI commands performed summer training with similarly organized and equipped 

active Army units. 

During the Inactive Training Period, National Guard regiments participated in the typical drill activities 

carried out by most Guard units. Like their active duty counterparts, these regiments often supported the 

training of their assigned divisions for some aspects of summer training. In other cases, elements were 

employed in improving the physical structures, roads, trails, and support facilities of their state’s training 

camps. Given their special skills, the Guard engineers were also often called up for disaster relief duties.

As with the RAI organizations, most of the Organized Reserve engineer regiments were functional 

units and were some of the most active and well-trained Reserve organizations in the Army. Several of the 

regiments had numerous members who were engineers by profession and belonged to various engineer 

firms and professional societies. An usually high number of the post-war commanders of Reserve engineer 

regiments had also commanded engineer regiments during World War I. Many other post-war reserve 

regiments were commanded by men who had been at least regimental executive officers during the war as 

well. Additionally, many of the company and battalion officers had served in France with engineer units. 

Thus, the high level of professional and wartime experience of unit leaders in many engineer regiments gave 

those organizations a distinct advantage not available to many other Reserve organizations. This experience 

and training was no doubt imparted to the many new lieutenants who joined these reserve regiments over 

the interwar years.

Engineer Battalions and Squadrons

Engineers of Troop A, 9th Engineer Squadron watch as men and horses of the 13th Cavalry ride by on their newly 

constructed bridge, Fort Riley, KS, circa 1937.

Engineer battalions and squadrons provided both routine and specialized engineer support to mobile units 

of the field army, corps, and division. Several also provided services to commands in the Communications 

Zone and the Zone of the Interior.

Organization

The organization and types of engineer battalions in the post-war Army were modified versions of 

many of the types of units that served in World War I. During the war, there were at least nineteen different 

kinds of specialized battalions, of which six were related to railroad operations and three were general or 

specialized construction units. After the war, the Army reduced the number to ten. This was accomplished 

by consolidating the functions of the railroad battalions into two standardized multifunctional units; 

consolidating the construction, forestry, and trades functions into auxiliary battalions (later redesignated 

as engineer battalions, separate); and transferring the sound and flash mission to the field artillery. The 

following table illustrates the allotment of the types of units to the various components through 1940.

Auxiliary and Separate Engineer Battalion TOEs.
1765

Railway Operating and Shop Battalion TOEs.
1766

The auxiliary engineer battalion was a general purpose organization. It consisted of a headquarters, a 

headquarters and service platoon, and four line companies. The battalion could perform basic construction, 

road improvement, and trade tasks such as logging, milling, electricity, and mechanics. There were six 

such battalions in each field army and three in each corps. These battalions underwent a minor T/O change 

in 1929 and were redesignated as “separate” battalions the following year. A significant number of these 

battalions were constituted in the Regular Army in 1927 and 1933 to replace National Guard and Organized 

Reserve battalions withdrawn from the field army and corps orders of battle and concurrently demobilized.

Railway operating battalions performed three basic functions: operation of railroad transportation 

equipment; routine maintenance of locomotives, cars, and other railroad equipment; and maintenance of 

tracks, sidings, and other structures of the railway. In light of those missions, the battalion consisted of a 

headquarters, a headquarters and service company, and three line companies consisting of one maintenance 

of way company, one maintenance of equipment company, and one operating company. The railway shop 

battalion performed the heavy maintenance and repairs of railway equipment. Its organization consisted of 

a headquarters, a headquarters and service company, and three line companies consisting of one machine 

shop company, one boiler repair company, and one car repair company. Both of these organizations 

were assigned to the Communications Zone or the General Headquarters Reserve. For mobilization and 

manpower purposes, the Organized Reserve battalions were affiliated with various railroad companies 

around the United States from which they would draw their personnel. The RAI battalions, however, were 

non-affiliated. 

Camouflage Battalion TOE.
1767

Camouflage battalions performed their missions for various purposes. Typically these battalions were 

used to hide large facilities and key locations, such as major headquarters and communications nodes, from 

enemy observation. The camouflage battalion consisted of consisted of a headquarters, a headquarters and 

service company, and three camouflage companies. One of these battalions was assigned to each of the field 

armies. One, the 40th Engineer Battalion, was assigned to the General Headquarters Reserve.

Topographic Battalion TOE.

Topographic battalions conducted topographic surveys and produced or reproduced maps for use by 

major command headquarters and mobile units. The battalion was composed of a headquarters, a headquarters 

and service company, one map reproduction company, and two survey companies. One of these battalions 

was assigned to each field army. Additional battalions were assigned to the Communications Zone and to 

the General Headquarters Reserve.
1768

Water Supply Battalion TOE.

As its name implies, the water supply battalion provided water resupply to mobile units of the field 

army. The battalion was composed of a headquarters, a headquarters and service company, and three water 

resupply companies. One of these battalions was assigned to each field army. Additional battalions were 

assigned to the General Headquarters Reserve.
1769

Heavy Ponton Battalion TOE.

Heavy ponton battalions provided bridging capabilities to span rivers and streams up to about 850 feet 

in width. These battalions were organized with a headquarters, a headquarters and service company, and 

two bridging companies. Each company could build two 216-foot bridges or one 432-foot bridge. These 

battalions were assigned to the General Headquarters Reserve and were to be attached to armies, corps, and 

divisions for specific operations. They would then be pulled back for refitting and reattachment for followon operations.
1770

Mounted and Engineer Squadron TOEs.
1771

The mounted engineer battalion provided light engineer capabilities to cavalry divisions. These 

battalions were originally organized with a headquarters, a headquarters and service platoon, and three 

mounted engineer companies. The battalion was reorganized in 1930 to consist of one animal-drawn 

company and the remainder of the battalion was motorized. Concurrently the battalion was redesignated as 

an engineer squadron. One of these units was assigned to each cavalry division.

Training

Only five of these specialized engineer battalions were active at any time in the Regular Army in 

the interwar period up to 1940. Only two, the 8th Engineer Battalion (Mounted) and the 29th Engineer 

Battalion (Topographic), were active for any lengthy period. By 1922, only these two battalions remained 

in the active force. Additionally, one troop of the 9th Engineer Battalion (Mounted) was active for the entire 

period. The two mounted units frequently participated in training exercises with the cavalry organizations 

that they supported. They both participated in various other key events as well. In some instances, they 

performed construction tasks, such as the flood wall around Marshall Field at Fort Riley, or other duties, 

such as the 8th Engineers’ mapping activities in the Big Bend district of Texas. Both of the units also 

helped train the RAI and OR engineer units of the Seventh and Eighth Corps Areas. The 29th Engineers 

were involved in numerous mapping projects as well, to include the Nicaraguan Canal survey in 1931 and 

the mapping of the Cascade region of Washington state. This battalion also assisted the training of OR 

topographic units from time to time.

The vast majority of the much more numerous RAI battalions were organized with Reserve personnel 

during this period. About half of them appear to have been functional units. The 40th Engineer Battalion, in 

particular, was a very active unit and in the 1930s frequently conducted joint training exercises with other 

OR and Guard units. Additionally, most of the RAI battalions were ordered to attend summer training as a 

unit at least one or more times during their period of existence.

Only one battalion and a few companies from some of the other battalions were ever organized in 

the National Guard. With the exception of the 127th Engineer Battalion (later Squadron) in Alabama, the 

remainder of these units were all relatively short-lived. The 127th Engineers participated in the usual armory 

drills and summer training periods typical of Guard units. It also survived long enough to participate in two 

Army-level maneuvers in 1938 and 1940. 

The great majority of the specialized OR engineer battalions were initiated sometime in the interwar 

period. Only about thirty percent of them, however, were functional. Most were too geographically 

separated to assemble for the Inactive Training Period. Some of the more active units, however, were the six 

mounted battalions/squadrons, a number of the corps auxiliary battalions, and most of the railway operating 

battalions. By the late 1920s, the six mounted battalions and many of the corps auxiliary battalions were 

concentrated in and around a single city making assembly for training meetings much easier. Due to their 

affiliation with civilian railroad companies, the members of the Reserve railway battalions, could assemble 

for training more easily than most Reserve or RAI units. The fact that they performed their wartime mission 

on an almost daily basis in their civilian occupations made them some of the more mobilization-ready 

organizations in the Army. About half of the Reserve engineer battalions were ordered to camp at least 

once during this period. Many of the functional battalions were ordered to camp about every other year. 

The personnel of those units not ordered to camp were usually attached as individuals to other engineer 

organizations.

 Special Troops

An unidentified divisional tank company on maneuvers in 1940.

Special Troops headquarters provided command and control for a diverse assortment of units that did 

not otherwise fit easily into other commands. These headquarters commanded most of these units in the 

field, but frequently attached them to other commands to support specific operations. The special troops 

commander typically functioned as the headquarters commandant and provost marshal for the command 

to which his headquarters was assigned. As such he was responsible for terrain management, traffic 

control, discipline, and security in the command’s rear areas. The special troops headquarters and staff also 

functioned as the rear command post for the command. US Army Signal Corps

Organization

GHQ Special Troops TOE.

As its named implied, the Headquarters, Special Troops, GHQ, was constituted to provide command 

and control capability for the special troops units assigned or attached to the General Headquarters. This 

command primarily controlled only those assigned units that supported the day to day operations of the 

General Headquarters in the theater of operations. 
1867

Army Special Troops TOE.

The Special Troops for the field armies as originally constituted in 1921 consisted of the following 

organizations:

 Headquarters, Special Troops, Army

 Headquarters Company, Army

 1 Military Police Battalion (Army)

 8 Service Battalions, Q.M.C.

 1 Field Remount Depot, Q.M.C. (1,200 head)

With the reorganization of the US Army to the four-army plan in 1933, the eight service battalions were 

withdrawn from the army special troops and in 1936, reorganized into the army’s quartermaster service 

regiment.

1928 Cavalry Division Special Troops TOE.

Though actually part of the infantry division quartermaster train, motorcycle companies were typically 

attached to the special troops due to their frequent use for courier duties for the division and brigade 

headquarters.

The special troops for both types of divisions underwent a number of changes during the interwar 

period. The first came on 15 August 1927 when a light tank company was added to the special troops for 

cavalry divisions. Concurrently the tank companies for the Panama Canal and Philippines Divisions were 

relieved from those divisions and assigned to the 1st and 2nd Cavalry Divisions, respectively. 

Originally, the service companies for the National Guard and Organized Reserve infantry divisions 

were constituted as part of the division quartermaster trains in 1921, but like the motorcycle companies, 

were typically attached to the special troops. Those for the Regular Army, however, were not constituted 

until 18 October 1927 for some unknown reason. On 3 June 1932, the service companies were officially 

assigned to the special troops. These companies were again reassigned to the new division quartermaster 

regiments in 1936, this time as lettered companies. None of the service companies for the active Regular 

Army or National Guard divisions were ever organized. Those for the RAI and OR divisions were almost 

all organized at some point during the interwar period. Virtually all the other special troops units were 

organized in one of the three components between 1921 and 1940.

The tank companies remained components of the special troops until 1940 when all Regular Army 

and National Guard infantry division tank companies, less that of the 11th Tank Company assigned to 

the Hawaiian Division, were relieved from their parent commands and integrated into one of the new 

separate tank battalions or armored regiments. The cavalry division tank companies were all disbanded. 

Those companies assigned to the OR divisions remained so assigned until disbanded in 1942 when those 

divisions were triangularized.
1871

Training

Regular Army special troops units were some of the best trained units of the interwar period, even 

if they were not the best equipped units. These separate companies were kept busy supporting various 

training events for other RA, NG, and OR units. The 1st Signal Company for example, supported training 

at the signal school at Fort Monmouth, for NG and OR signal companies, for the training activities of the 

1st Division, and for various corps area and army CPXs in the 1920s and 1930s. The company’s training 

support extended to reserve units from several other corps areas other than its own. The several Regular 

Army active tank and ordnance companies scattered across the United States performed similar duties for 

NG and OR divisional and non-divisional tank and ordnance organizations as well. Unfortunately, much of 

the equipment these units possessed was of World War I vintage up until the late 1930s.

The training experiences of National Guard special troops units were typical of those for other Guard 

units: weekend or week night drills during the inactive training period followed by a two-week camp in the 

summer. In a few instances some tank companies conducted training some years with Regular Army tank 

companies away from the division camp due to the lack of actual tanks at their home station or division 

training areas. Similarly, some ordnance companies did the same. Most special troops units, however, 

performed their summer training at the same time as the bulk of their parent divisions. In the case of multistate special troops commands, the separate companies usually attended training with its state’s other NG 

units. 

Training for the special troops of OR divisions was uneven at best. For those instances where the 

command’s units were concentrated in a single city, the special troops often organized some level of unit 

training during the inactive training period. Frequently, the personnel from the special troops would attend 

training sessions set up for their specific branch. In cases where the special troops were spread out over 

the division area, the units did no unit training during the inactive training period. These personnel usually 

attended training with other units, or troop schools for specialized or branch training conducted at, or near, 

their home location. During summer training, most companies, less the tank companies, usually attended 

branch training conducted at a Regular Army installation specifically set up for reserve personnel. In 

some instances they conducted training with Regular Army or National Guard special troops units. Tank 

companies almost always conducted summer training with Regular Army or National Guard tank units.
